The study of growth and development of Hedysarum alpinum L. in non-chernozem zone of Russian Federation

For providing stable domestic source of raw materi-als of production "Alpizarina" (preparation of antiviral action) there was a need for industrial cultivation of Hedysarum alpinum L. as in nature in the central region of the Russian Federation plants are seldom met and generally on mineral peat soils. The maximum mainte-nance of mangifirin, the main active ingredient, is ob-served in leaves and inflorescences. Reproduction of Hedysarum alpinum L. was carried out by seedling way. For the purpose of strengthening the growth processes of Hedysarum alpinum L. not root top dressing by binary mix organic and mineral fertilizer EcoFus with microfertilizer of Cytovit was carried out. The obtained data showed the efficiency of applied preparations for strengthening of growth processes at plants of Hedysarum alpinum L. The growth of plants on the se-cond year of vegetation was noted at the end of April - the first decade of May. The supervision over the plants of Hedysarum alpinum L. of the second year of vegeta-tion showed that, despite adverse weather conditions, plants successfully passed the main phenological phas-es. Gathering of Hedysarum alpinum L. on medicinal raw materials was carried out to the phase of the begin-ning of blossoming. Productivity of dry elevated mass of Hedysarum alpinum L. second year of vegetation made 1.13 kg / 10 sq.m, the phytomass of leaves and inflores-cences made 0.62 kg / 10 sq.m. The period from the beginning of growth prior to collecting seeds made 90-95 days. The first gathering of seeds was carried out at 2/3 ripened seeds on the main inflorescence (August, 9), on lateral shoots, fruit were in the phase of dairy and wax ripeness. The productivity of seeds of the main inflorescence made 22.7 g/m2, thus the quantity of ma-ture seeds made 80 %. In the conditions of nonchernozem zone of the Russian Federation Hedysarum alpinum L. passes all phases of develop-ment and is perspective for cultivation.
